UPPER MIDWEST THIS WEEKEND...
...LINGERING SHOWERS FOR PARTS OF SOUTHERN NEW
ENGLAND/MASSACHUSETTS CAPE THROUGH SATURDAY MORNING...

ALOFT, A CLOSED LOW PRESSURE SYSTEM WILL LIFT FROM THE SOUTHWEST
INTO THE GREAT PLAINS THIS WEEKEND. A COLD FRONT WILL BE THE FOCUS
FOR SHOWERS, THUNDERSTORMS AND ANOMALOUSLY COOL WEATHER OVER
PORTIONS OF THE CENTRAL U.S.. TONIGHT, SHOWERS AND THUNDERSTORMS
WILL CONTINUE ACROSS THE SOUTHERN HIGH PLAINS. A SLIGHT RISK OF
SEVERE THUNDERSTORMS IS IN EFFECT ACROSS PARTS OF EASTERN NEW
MEXICO AND WEST TEXAS. CLUSTERED STORMS MAY PRODUCE LARGE HAIL,
SPORADIC STRONG/SEVERE GUSTS, AND A TORNADO OR TWO, ACCORDING TO
THE STORM PREDICTION CENTER. THE HEAVY/EXCESSIVE RAINFALL AND
SEVERE THUNDERSTORM THREATS SHIFT INTO THE CENTRAL/SOUTHERN PLAINS
AND MIDDLE MISSISSIPPI VALLEY ON SATURDAY AS THE SURFACE COLD
FRONT INTERACTS WITH MOISTURE FROM THE GULF OF MEXICO.
TEMPERATURES ARE LIKELY TO FALL PRECIPITOUSLY ON THE BACKSIDE OF
THE COLD FRONT OVER PORTIONS OF THE SOUTHERN HIGH PLAINS AND
CENTRAL PLAINS BEGINNING SATURDAY. HIGH TEMPERATURES IN THE 50S
WILL REPRESENT 15 TO 30 DEGREE DEPARTURES FROM AVERAGE FOR THE
AFOREMENTIONED AREAS. ABOVE AVERAGE TEMPERATURES WILL BE IN PLACE
ACROSS THE MIDWEST AND SOUTHEAST THIS WEEKEND AS UPPER-LEVEL
RIDGING CENTERED OVER THE WESTERN GULF COAST REMAINS IN PLACE.
ELSEWHERE, RAIN SHOWERS WILL CONTINUE ACROSS SOUTHERN NEW
ENGLAND/THE MASSACHUSETTS CAPE TONIGHT THROUGH SATURDAY MORNING.
